Answer:
See below for answers and explanations
Explanation:
Given P(-3,4) we can solve for the third side:
c=√[(-3)²+4²]
c=5
If the terminal side of ø in standard position contains the given point, then it is located at that point, making -3 the opposite side (the side length is 3), 4 the adjacent side, and 5 the hypotenuse.
Therefore:
cos∅=adjacent/hypotenuse=4/5
sin∅=opposite/hypotenuse=3/5
tan∅=opposite/adjacent=3/4
